@skimlines Do you mean David Attenborough? True, much of his work is associated with BBC, but he is much more than his voice. Morgan Freeman’s voice would also work here…
@mathlover I have seen laptops used for 8 years. 12 is quite a lot, especially if it was powered on most of the time. I understand the attachment, but please know that the machine is already a champion who may have no choice but retire.
@mathlover support.hp.com could help in this instance. It will ask you the model number (with indications for where to find it) and then will allow you to look at the user manual. It does so for more recent hardware. The manual should have some troubleshooting steps. FN keys work for both desktops and laptops. The manual can even point out to a self-check for hardware. Once that is ruled out, it will tell you how to choose a different boot device(to fix a bad update).
@mathlover F3? F10? Sorry, it’s usually one of these four for most laptops. You could look at HP support site, trying to find the exact info for your hardware, but that takes more time…
@mathlover Try hitting F2 or F9 at power-up. It should enter into Bios and allow you to list the hardware. Simply exit then, without changes. If that happens, most likely it’s an Ubuntu update that broke the bootloader. Otherwise it may be a hardware fault. If at boot it beeps a number of times, then it’s a hardware fault. You could google “hp N beeps at startup”, you can find what it means.
